From their announcement:
The Gothic Terrain: Tank Traps are finally here! You get a set of ten pressure cast resin tank traps measuring 23x23x20mm for $10 -- a bargain given the amount of resin going into these bad boys.
I am also happy to announce that the original straight side Runic Mountain sculpts have been remastered with a beveled edge -- effectively doubling the available Runic Mountain selection!
Both products are available for immediate purchase at the Secret Weapon store.
